between {berryFunctions}  R Documentation 
Are values within a certain interval?
Basically a wrapper for x >= a & x <= b
to save repeating long x names twice.
between(x, a, b = a, incl = TRUE, aincl = incl, bincl = incl, quiet = FALSE)
x 
Numerical vector 
a, b 
Numerical values/vectors specifying the borders of the interval.

incl 
Logical. Include values on the borders? For x == border, TRUE
will be returned. Specify per left and right border separately
with the arguments 
aincl, bincl 
Logical. Include values on left and right border, respectively?
DEFAULT: 
quiet 
Logical. Suppress warning if a>b? DEFAULT: FALSE 
Logical (boolean) vector with TRUE/FALSE values
